Rotation: movement of an object around it's axis
2. Because the earth rotates, winds are deflected from the path of a straight line.
3. They are directly proportional. As mass increases, luminosity increases.
4. The average temperature is affected by the proximity to water because of the difference in the specific heat of land vs. specific heat of water. Water takes longer to heat, keeping summers cool and radiates heat slowly, keeping winters mild.
5. Air masses have properties associated with humidity, temperature and pressure. An air mass gets those particular properties based on where it forms.
6. Europe and N. America have moved away from one another over the past 250 million years, east and west respectively. They move in convection currents within the mantle.
7. A greenhouse gas absorbs radiative heat from the earth and prevents it from escaping. Carbon Dioxide and Methane gas (along with water vapor) are a few greenhouse gasses.
8. The LCL of a cloud is the altitude at which an air parcel forms a cloud.
9. In order from the surface to the interior: Lithosphere, Moho, Asthenosphere, Stiffer Mantle, Outer Core and Inner Core.
10. P waves can travel through solid, liquids and gasses while S waves can only travel through solids.
11. What are the air mass names and where do they form?
maritime polar- northern waters. maritime tropical- souther waters
continental polar- inland, canada/alaska continental tropical- inland, mexico/nevada
continental arctic- either on land or in water, north of arctic circle
12. The thinnest crust is in the ocean despite the densest rocks found in the ocean.
13. Lighter colors and lower densities are associated with felsic rocks.
14. On June 21st, because the angle of insolation will be its highest since the sun will be at it's zenith.
15. As the angle of insolation increases, the temperature increases.
16. Movement of tectonic plates have moved continents to different latitudes and therefore, the continent has gone through a climate change.
17. Fracture: the uneven breakage of minerals
Cleavage: the even breakage of minerals- associated with flat planes (calcite, halite, galena)
18. Normal faulting make rock layers drop down while reverse faulting makes rock layers thrust upwards.
19. 2.6x10^9 (2,600,000,000)
20. A continental polar air mass causes lake effect snow.
21. The oldest rock layers are on the bottom of stratified layers.
22. An influx of fresh water would disrupt the thermohaline circulation by shifting upwelling zones, potentially causing the failure of fishing industries.
23. Gravity causes the dust and debris to start condensing on itself, increasing the mass and energy of the center of the nebula.
24. Contact metamorphism: contact of heat from partially melted rocks.
Regional metamorphism: the intense pressure and heat associated with mountain building (friction)
25. Sediments are deposited in horizontal layers.
26. Density drives weather systems, convection currents and energy transfers within our earth system.
27. EM and Mechanical waves travel in the same way- they both have crests, troughs, waves and can be measured in frequency. Mechanical waves need a medium to move, however, and EM waves do not.
28. If forces are balanced, an object does not move. Only when forces are not balanced does an object move.
**REMEMBER: Gravity depends on two things: 1. Mass 2. Distance**
